The MC is ridiculously OP in this, yes. In fact, nothing short of gods could even touch him. But he's very... how should I put it, undercover?
He doesn't like to be noticed, and uses alias from early on to mask his activities.
This kinda develops into a very unique element that defines it separate from other Narou novels.
Spoiler:
He currently (as of the latest development) mainly uses three primary identitles:
Sato: Primary identity. Young upstart noble, a generous philanthropist who is both an accomplished adventurer, owner of an orphanage, and amazing chef. Speech pattern: Gentleman.
Nanashi: Mysterious Hero of the kingdom, who hides behind a mask. Revered by the king as Nanashi's girlish face is the same as the founder of the nation, Yamato (The king believes Nanashi is Yamato reborn). In truth, Nanashi's face is Sato's childhood friend and co-worker which he chose to use without realizing it's the same as Yamato. When Sato wants to do something powerful publicly, he uses Nanashi identity to accomplish it. Speech pattern: boyish and mischievous Trap.
Kuro: Dresses in all black, Kuro is Sato's underground identity. When Sato rescued adventurers forced to work in a terrorist plot, he had to hide them from the authorities as they would be considered guilty (even though it was against their will), so he created an identity for underground activities. He runs many (some shady) business under this alias, and revered by those he saved and employed. Speech pattern: Matching his look and name, a brooding and commanding boss.
It's kinda interesting because it almost feels like having three different protagonist, although they are all the same person.
